Question:
Reportability--Melanoma: Is "early" melanoma reportable? See Discussion.
Discussion:
Because "evolving" melanoma was never reportable, this issue only relates to "early" melanoma.
Answer:
For cases diagnosed 2018 to 2020, early or evolving melanoma is not reportable.
Evolving melanoma (borderline evolving melanoma): Evolving melanoma are tumors of uncertain biologic behavior. Histological changes of borderline evolving melanoma are too subtle for a definitive diagnosis of melanoma in situ. The tumors may be described as "proliferation of atypical melanocytes confined to epidermal and adnexal epithelium," "atypical intraepidermal melanocytic proliferation, "atypical intraepidermal melanocytic hyperplasia"; or "severe melanocytic dysplasia." Not reportable.
